SELECTIVE GUM'MED-TAPE-DISPENSING MACHINE.

Application filed November 28, 1925. Serial 10. 70,871.

My invention relates to machines for the dispensing of gummed tape, theta e dispensed to be used in the wrapping packages and the like as asubstitute for. cord or string, and has for its object the carryingwithin the frame of one or more widths of tape, power means fordispensing the same and selective means for dispensing the width of taperequired for the package or article to be wrapped.

A further object of my machine consists in providing means within themachine for moistening the gummed surface of the tape, as the same isbeing dispensed.

A further object of my device, consists in providing a manipulating handmember adapted to complete an electric circuit, by the same beingdepressed selective means is provided for selecting the desired width ofthe tape to be dispensed, and when the circuit has been completelybroken and the desired amount of tape having been dispensed, the returnof the hand member to normal position, will automatically cut the tapedispensed through the action of the shearing blade carried on the lowerend of the same.

A further object of my invention, consists in the arrangement of theparts in such a manner that the cutting of the tape ismade upon theunmoistened portion of the tape.

With these and incidental objects in view, the invention consists incertain novel features of construction and combination of parts, theessential elements of which are set forth in the appended claims, and apreferred form of embodiment of which is hereinafter shown withreference to the drawings which accompany and form a part of thisspecification.

Like reference characters refer to like parts throughout the severalviews.

1 is the base of the machine, having side wall frame .members2, disposedupon either side of the base and extendin practically vertical from thebase. A sha t 3, is maintained within the side wall members 2, insuitable bearings and is held in position by thumb nuts 4 and 5,disposed on either end of the same. Mounted upon this shaft are one ormore rolls of gummed paper, here shown as two in number, as shown at 6and 7 the same being positioned upon the shaft by a spacer 8, which issecured to the wall structure of the machine by a suitable fasteningmeans as a screw 9. Different sized spacers may be used to accommodatedif-v ferent width of rolls. The gummed paper is conducted from the rollthrough channel guideways or tubes 10 and 10', and passes etween thefeed rolls 11 and 12 and 29 and 29. The lower feed rolls 11 and 29* aremounted on a rocking su port or yokes 11 and 29 respectively, w ich arerockabl mounted about shaft 13, secured to the sid e wall members of themachine. A power unit 14, as an electric motor, is mounted upon a basesupport 15, within the frame structure and is energized through anelectric circuit, through the electric cords 16 and 17, which areconnected to an outside source of electric energy.

When it is desired to secure gummed tape from the machine, the o eratinhandle or knob 18, is lowered by t e han of the o orator. If it isdesired to secure a wi e tape, the operating handle which is freelymounted on the sliding stand 24, is turned until the contacting arm 19,is made to engage with the trip 20*, which is normally held in raisedposition through the action of compression spring 21, su ported u onthebracket 22, at which time t e lower eed closing the electric circuitto the power unit 14, is then energized, turning the armature of themotor and the worm 26, WhlCh 1s se cured to the shaft thereof. The worm26, engages the worm wheel 27 which is mounted on the shaft 27 A whichis rotated thereby. The shaft 27 also carries thefeed rolls 29, and 12which are rotated thereby, the roll 29 feeding the wider gummed tapefrom the roll 7. The side wall members 30 and 30 are positioned parallelto each other, and are spaced apart sufiiciently to permit the stem 24,to freely slide therebetween. The side wall members are each providedwithiopenings of size and shape equal to the size and shape of theinterior of the tubes 10 and 10 The lower end of the stem 24 1sbroadened out into a rectangular plate 24", and the holes 28 and 28 areformed through. this plate. The lower edge of each of the holes 28 and28 are formed at an angle to the horizontal as shown at 28 and 28 toform the cutting edges or knives of my devlce. The normal position ofthe stem'24, is such that the holes 28 and 28 are positioned above thetubes 10 and 10. In operation the knob 18 is depressed, which depressesthe plate 24 so that the holes 28 and 28 will register with the tubes 10and 10 and tape will pass through one or the other of the holes throughthe plate 24; and if the knob is released, the stem 24 and the plate 24will rise to normal position, brou ht about by means of a spring 38,hereina ter described, the electric circuit to the motor 14 will beopened and the motor and machine stopped, and the paper strip passingthrough the machine will be cut by one or the other of the cutting edgesor knives 28 and 28 as the case may be. The depression of the knob orhandle 18, depresses the stem 24, also, and in doing so, the openings 28and 28*, are made to register with the openings 10 and 10 through theside wall members 30 and 30 which form a guideway for the stem and whichis best shown in Fig. 8. This permits the gummed tape to pass throughthe opening 28.

A liquid, as water, is contained within the basin 31, in which thewetting roll 32, rotates. The tape comes in contact with the wettedroller through the action of a holding down roller 33, disposed abovethe roller 32. The roller 32 is freely mounted upon the shaft 37, androtation is imparted to it by engagement with the roller 33 which isrotated by means hereafter explained. The shaft 37 mounting the roll 33,is revolvably mounted to the outer ends of each of the arms 37 and 37the inner ends of said arms being loosely mounted to the shaft 27. Anengaging train of revolvable gears 34, 35, and 36 are mountedrespectivel 1 to the shaft 27', to the arm 37 intermediate its ends, andto the shaft 37; and it will be seen that when the shaft 27 is rotated,shaft 37 with its associated roll 33 will also be rotated. The roll 33normally rests upon and rotates the roll 32, and will rotate roll 32when it, itself is rotated. The paper strip passes between the two rolls33 and 32 when they are rotating, and as the strip passes between therolls, the under or coated side of the paper will receive moisture fromthe wetting roll 32.

Moistened tape of the selected width will be dispensed through thistrain of movements and over the wetted roll until the desired length hasbeen secured, at which time the operators hand is removed from "the knob18, which permits the return of .the stem 24, which breaks the circuitand stops the motor on the upward movement of the stem, which is causedby the action of the compression spring disposed about the stem, asshown at 38. The spring 38 is compressed on the downward movement of thestem and which automatically returns the stem to normal position whenthe knob 18 is released.

Should it be desired to dispense the narrow gummed tape, the contactingarm 19, is moved to engage with the trip 2O as best shown in Fig. 5, atwhich time the same train of operations are set in motion,

with the exception that the hinged feed roll 11, disposed beneath thewide gummed tape to feed the same, is disengaged from r01 12, andthewide tape 7 is not drawn from the roll and upon the actuation of themachine the narrow tape 6 only is dispensed.

Should it be desirable to dispense both narrow and wide at the sameoperation, the same may be accomplished by the permitting of thecontacting point 19, to be clepressed without contacting with either ofthe rolls at which time the same train of mechanisms will be set inoperation, with the exception that both narrow and wide gummed tape willbe dispensed to the re quired length, after which time the train ofoperations are stopped and the hand devices are permitted to return tonormal position, at which time both narrow and the wide gummed tape aresheared off on the return of the hand device.

The hand device may be rotated within certain limits, the movement ofwhich is governed by the stop pins or guides 40 and 41, disposed ateither side of the same. To facilitate the engagement of the contactingarm 19, with either of the trips 20 and 20 emma the stop pins 40 or 41,and when depressed is positioned directl over the trip for dis engagingone of t e feed rolls. This is shown in the position of the contactingarm 19, engaging with the stop pin 40, in Fig. 4. The arm 19 being shownin dotted position.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment herein shown and described, as it is susceptible ofembodiment in various forms, all coming within the scope of the claimswhich follow.
